Uzebox with SCART Interface
February 6th, 2010 at 1:44 pm

European Uzebox fans rejoice! From Russia comes a new version that uses the ubiquitous SCART TV interface. F0lken has successfully tested his design and no kernel code change was required. Moreover, it also means an even more retro-minimalist Uzebox since the AD725 is not required! Get his schematic here,  important information on the Wiki and check out his forum thread for more details.

GDB Support Added to the Uzebox Emulator
January 6th, 2010 at 8:22 pm

Good news everyone! Thanks to Filipe Rinaldi, the Uzebox emulator now implements an internal GDB server (originally based on simulavr) making it an important tool to develop Uzebox games. You can use many debugging clients like avr-gdb (command line),  avr-insight & KDbg (GUI frontends) or even Eclipse to help troubleshoot your games. Visit the Emulator Wiki page for more details.

LePlatz - A Level Editor for the Platz Engine
January 4th, 2010 at 1:08 pm

Paul McPhee released LePlatz, a level editor for the Platz toolset (supporting Platz v1.0). LePlatz eliminates the tedious task of converting images of your game world into textual data structures. LePlatz provides a GUI with a set of tools corresponding to the logical structure of the format expected by the Platz toolset. You simply need to draw shapes on your game world canvas and LePlatz does the rest. Read about its features and download here.

About

The Uzebox is a retro-minimalist open source game console. It is based on an AVR 8-bit general purpose microcontroller made by Atmel. The particularity of the system is that it uses an interrupt driven kernel and has no frame buffer. Functions such as video sync generation, tile rendering and music mixing is done realtime by a background task so games can easily be developed in C. The design goal was to be as simple as possible yet have good enough sound and graphics while leaving enough resources to implement interesting games. Emphasis was put on making it easy and fun to assemble and program for any hobbyists. The final design contains only two chips: an ATmega644 and an AD725 RGB-to-NTSC converter.

Current Features
  • Low parts count and cost: The system is made of only two chips and discrete components.
  • Interrupt driven kernel: No cycle counting required, sound mixing and video generation are all made in the background.
  • 256 simultaneous colors: Accomplished by using a R-2R resistor ladder DAC.
  • 4 channels sound engine: The sound subsystem is composed of 3 wavetable channels and 1 noise or PCM channel.
  • MIDI In: With a music sequencer, allows the creation of music directly on the console.
  • Retro controllers: The joypad inputs uses standard NES/SNES controllers interface.
  • SNES Mouse Support
  • SD/MicroSD card interface
  • Expandable: I/O lines and peripherals are still available, like the UART and SPI port for one to experiment.
  • Emulator: A fully, cycle-perfect, emulator was developed and greatly eases development.
  • Gameloader (beta): Load and flash games stored on SD cards!
  • API: Develop games using an API that provides multiple video modes, sound driver and more.
  • Open Source: The software and hardware design are totally free and licensed under the GPL.

Showcase

These videos demonstrates some of the features of the Uzebox. The first one is a Tetris clone named "AVR Megatris". The game is fully functional and implements most of the official "Super Rotation System" (SRS) system complete with hold block, t-spins and ghost piece...it even plays classic Tetris songs!
